Cuong Manh Le 7b314d27ce cmd/compile: fix bad order of evaluation for multi-value f()(g()) calls 
The compiler use to compile f()(g()) as:

	t1, t2 := g()
	f()(t1, t2)

That violates the Go spec, since when "..., all function calls, ... are
evaluated in lexical left-to-right order"

This PR fixes the bug by compiling f()(g()) as:

	t0 := f()
	t1, t2 := g()
	t0(t1, t2)

to make "f()" to be evaluated before "g()".

Fixes #50672

README.md

The test directory contains tests of the Go tool chain and runtime. It includes black box tests, regression tests, and error output tests. They are run as part of all.bash.

To run just these tests, execute:

../bin/go run run.go

To run just tests from specified files in this directory, execute:

../bin/go run run.go -- file1.go file2.go ...

Standard library tests should be written as regular Go tests in the appropriate package.

The tool chain and runtime also have regular Go tests in their packages. The main reasons to add a new test to this directory are:

  • it is most naturally expressed using the test runner; or
  • it is also applicable to gccgo and other Go tool chains.
